DBX67.0
Invert handwheel direction of rotation active (machine axes)
Edge evaluation: No Signal(s) updated: Cyclic
For a handwheel, which is assigned to a machine axis, this signal indicates whether the direction of
rotation was inverted:
Signal = 1 The direction of rotation of the handwheel is inverted.
Description
Signal = 0 The direction of rotation of the handwheel is not inverted.

Bit 0-2
JOG - Approaching fixed point active
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
Message to the PLC that the function "Approaching fixed point in JOG" is effective.
The selected machine axis can be traversed to the specified fixed point binary-coded via Bit 0-2
with the traverse keys or the handwheel.
Signal state 0 or
edge change 1 → 0
"Approaching fixed point in JOG" is not active

JOG - Approaching fixed point reached
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
Message to PLC that the selected axis has reached the approaching fixed point with "exact stop
fine" by virtue of the traversing motion in JOG.
This display signal is also signaled if the axis reaches the fixed point position in the machine
coordinates system via other methods e.g. NC program, FC18 (for 840D sl) or synchronized action
on the setpoint side and comes to a standstill on the actual value side within the "Exact stop fine"
tolerance window (MD36010 $MA_STOP_LIMIT_FINE).
Signal state 0 or
edge change 1 → 0
The axis has not yet reached the approaching fixed point.
